Latest update.. We finally found the remnants of a stern # on both boats, the same day the CG came through with the transfer records from TRACEN Alameda to TRACEN Petaluma. The hulls are 31012 and 31014. Paint removal is complete on 14 and a new 165 psi fire pump was purchased. A beautiful Fire Moni...

The "RT" is for Reserve Training. I found a Disposition log for 1985 and 31001-2-3 were still in service with 31004 de-commissioned. My 2 "wantabe" hulls turned out to be 31014 and 15. 31015 should be in the water as soon as the crane gets fixed....It's always something slowing you down. Thanks, Ste...

USCG Bertram 31 Mystery Solved The Coast guard purchased 4ea. 31' foot Bertram Convertibles in 1964. They Numbered them as 31001 through 31004. Then wrote a specification in 1966 and produced their own boats in the USCG Yard in Baltimore in 1969. They CONTINUED the 3100X numbering series AND INCORR...

Head back from the author of United States Coast Guard Harbor Patrol Fleet 1924-1980 Kennneth Suterland and I quote" The Builder of 31001to 31004 was Bretram in 1963. Hulls 31005 through 31028 were Coast Guard Yard starting in 1964" This 5 full years earlier than I thought and predates the Bertram P...

Found another Bertram reference "Naval Institute's Guide to the Ships and Aircraft of the U.S. Fleet 18th edition" Page 609 Has the first 4 boats with hull # 31001 through 31004 made at the Bertram Co. Miami Fl. Possibly in a development or prototype group of Bertram? Even so, they were USCG designe...

Good eyes! see if the owner knows the original Coat Guard Hull Number they ran From 31001 to 31029. I just scored a hit from the USCG Historians office and they will copy all of documents they have. If there are orders for Bertram in '68 then we'll know a little about the early prototypes. But the m...

Yep...Now if the Easter Bunny will tell me the hull numbers, the Tooth Ferry will help me get them documented by the US Coast Guard.....OH wait....they're the ones that messed up the old numbers....Catch 22 anyone?

Just got a PDF from the Coast Guard History folks, check it out at; www.uscg.mil/history/boats/docs/31FootPSB.pdf Quoting now "CG-31001 through CG31004 were built by Bertram Boat Works, Miami, FL. CG-31005 through 310019 were constructed at the CG Yard at Curtis Bay, MD." Also says Single engine and...

Found a Jan 1969 USCG Reservist Article on the boats..looks like at least 22 of them were made and I quote "The Coast Guard Yard has completed four prototype 31' Port Security Boats" so even though the fiberglass IS GREEN and everyone in the Coast Guard calls them "Bertrams" I'm siding with the guys...

From an E-mail by R.Wyco of USCG I remember those boats, we used them here at the training center Yorktown VA to teach students single screw theory. I spent time on them here at the dock mooring and unmooring while attending Boatswain mate A school as a student in 1983. (eye witness) (My speculation...

Well the plot thickens...Here is a reply I got from the USCG Historian.. Mr. Wilson, We do not have histories on individual boats. The 31-foot Port Security Boats were built by Bertram and the CG Yard. I am in the midst of building pages on small boats and have not done one for the 31-footer. It wil...

Well, we got lead into the "Bertram" direction by the caption at the bottom of the USCG photo. Dang, and I had memorized the "I must rebuild a Bertram 31" video. Thanks for all the help...I have some inquires in at the Baltimore Coast Guard Yard to see if they know anything about these. Thanks, agai...

Well, sort of... the V bottom is interrupted at the prop shaft exit and the stern is arched at the center-line by about 4 inched above the closest chines.
Another feature on the stern is a slight "V" like they were trying to make it "Double Ended" or reduce the splash from a following sea.

Yep, 6-53 Detroit setting right down the middle with a 20" prop. should like 18 knots or so at cruse. Notice the "Head Lights", our boats have these locations defined in the hull, but no lights were ever installed. The cabins are bare-bones and everything is as heavy and thick as you would expect fo...

http://www.coastguardpics.net/sitebuildercontent/sitebuilderpictures/31009bertramreserveboat_resize.jpg The Coast Guard had 2 of these burried up to the water-line in a parking lot. They are in amazingly good shape for being "Training Aids" for the last 25 years. We have one of them running after o...
